feat(widget): add interactive notes widget

[loloakira]

Description

This PR adds a new home-screen widget called Interactive notes — a third widget alongside the existing single-note and note-list widgets, which are left unchanged.

What it does

• Shows notes as a scrollable single column of rounded cards.
• Each card shows the note title and a multi-line content excerpt (the whole note when it is short).
• Tapping a card opens that specific note; a floating "+" button in the bottom-right creates a new note in the widget's configured category/account.
• The favorite star is shown as a non-clickable indicator.
• Reconfigurable via long-press on Android 12+, with a live previewLayout in the widget picker.

Implementation notes

• Reuses the existing NotesListWidgetData storage and excerpt generation - no database migration.
• Sort options are stored in per-widget SharedPreferences; notes are sorted in memory.
• One shared change: WidgetNotesListDao.createOrUpdateNoteListWidgetData now uses @insert(onConflict = OnConflictStrategy.REPLACE) instead of a plain insert that aborted on the existing primary key, so reconfiguration can persist updated settings. This is transparent to the two existing widgets, which are not reconfigurable and never hit the conflict. A DAO test covers the upsert.
• New source strings were added to values/strings.xml only (translations are handled by Transifex).
• The two existing widgets and the shared data layer are untouched.
• Added the explicit "Add widget" button so that saving is no longer triggered by tapping a category.
• Added section headings and preselected "All notes".

Tested

• ./gradlew assembleDevDebug and ./gradlew lintDevDebug pass.
• test DAO + assembleDevDebug/lintDevDebug pass
• Manually verified on a device (Android 16): open note, create note, sort options, reconfiguration, light/dark mode.

Awesome!

Just a smal UX thing:
When I first set it up, I was unsure how to "save".
I had to click on "all notes" (or Favorites).
I am a bit unsure how to make this more understandable?
Maybe via a radio button and a real "save/add" button?

@jancborchardt do you have an idea?

[loloakira]

Thanks!

I don't like it either but as it was my first PR for this project I didn't want to change too much things. I reused the interface of the previous widget that wasn't editable but where the saving was done on selecting the category.

[tobiasKaminsky]

I understand.
Let's see if @jancborchardt has a good idea, which does not require too many changes.

Looks very nice, and useful! :)

Regarding the settings, some details:

• Settings regarding favorites on top and sorting could just follow in-app preferences. Either they can be used as a preset here, or we don't need to show them at all here
• "All notes" could be preselected, and yes I would say a specific FAB in the bottom right saying "Add widget" would be nice (needs to be ("Edit widget" when editing of course)

[loloakira]

Thank you!

I had a little time to make those changes and upgrade the project to the last main commit.

• I fixed the minSdk part in my widget and modified the saving menu.
• I added a FAB.
• I added titles to understand the different parts and made "All notes" selected by default. It's now a selection before saving the widget with the FAB and not a saving on selecting the category.
• I checked the default configuration parts but found no place where the the newest/oldest and favorites on top are so I just let favorites on by default like the rest of the app.
• I used the US form and not UK form for "Favorites" instead of "Favourites".

Now I like this menu. Tell me if it's ok.
